A familiar story with questions. VI

[RR17]

So I'm in a bit of a crossroads here.
I just went to breakfast with W. Both Ds didn't want to go. It was pleasant, nothing special.
But immediately after returning W knocks on my MBR door and says she is running down to her office to get some paperwork ready because a new hire is coming on in the morning. I replied "Okay". I sometimes think she does these things to restore trust.
Ws office is only like 3 miles away. She has a work friendship with a younger guy that is not her type but gets brought up too often in stories. I have expressed concern and W has assured me that there is nothing inappropriate.
It is a small office and who knows?

So my dilemma, Do I drive down there and look for her car at the office?
Most of the time I don't feel suspicious, but every now and then...

When a bond of trust has been abused and the proper steps to repair the damage are not taken, I expect this will continue to haunt me.
